To all 'whom 'it 'may concemi Be lit known that' l, Noimis C. lroanns, a citizen oit' the United States, and a resident of Newburyport, County of Essex, State' of lvlassachusetts, have inventedan improvement in Hoisting-Hoolrs, of Which the following is a specilication.- l

This invention relates to a specicforin of lifting hook which is especially designed and adapted for use in connection with a block and tackle, in lifting an automobile engine from its bed, the particular device illustrated heilig esp cially adapted to be engaged With a Ford engine, although it maybe modif. tied for-use in connection. with engines of other makes.

The object ot' my inventiony is `to provide av forro of lifting; hook, `which is 'of simple construction, so that itA can be manufactured at small expense, which is strong and dura ble so that it cannot get out ot' orden,` which is adapted to' be readily connected to, and disconnected from 'the engine and which, when connected, cannot'beeorne disconnected through accident.

I accomplish theseobjeets by the means shownA in the accompanying drawing, in 'which Figures l, 2 and are side elevations of a lifting hooi; embodying my invention and qbowing the manner oi application to an en.

cylinder.

n ig. ifs an. end vienT thereof, and l? 1g. 5 is a detail view olf the connecting pin which 'l einploy.

.As shown in the drawings, l provide a sti' iron liar, which is' forged into loopshaped` 'forni to provide a pair oi depending arms a and b, which extend divergently troni the suspension point and lie in thev saine plane. The arm a is provided with a toe a at its lower end, which extends inward' te-` Ward the other arm at approximately right anglesthereto., and 'the'arin is provided with a hook b, which is extended at right angles to the' plane of the arms, and formed to provide a, semi-oireular recess. Zi, therein.. il. locking; pinc oi' i' material, isalso provided, said pin comp .ising a cylindrical. portion o', which adapt-ed to lit easily into one of the ports oi' the cylinder, and 'a portion. o2, ci? smaller diameter, forming a square. shoulder The diameter 'of the portion c2 is slightly less than the diameter of the recess o2 inclosed by the hoch if. so

that said portion e may be passed into said hooi.; /cand be held therein. y

in practice thedistance between the'end .of the toe a and the side of thehoolr" isposition ofl .F 2, the device is moved edge- Wise so that. the 4toe engagesl beneath4 said ledge, as in the dotted line position of Fig. 2.-

lhe manifold having been removed, the l larger portion' of the pin o is inserted in a cylinder port, as indicated-in-Fig., 3, and the smaller portion is engaged in the hook 6'., as

shown in Fig. 4:, the arrangement being such i that, when 'the arm a is engaged Withl the edge ofthe flange oit the cylinder,the. side ofthe' hook E will belengaged vwith the shoulder c3 of the pin, and-,as the pin cannot be moved inward beyond the pointindicated in 3, it Will he apparent that the device,

as a whole, will be looked against lateral movement.

.lis the pin c cannot be tilted to a materiali' .nt in. the'aperture in which itis inserted, if 'i 'the device is pulled upward, it Will torni as rigid a connection between the arm t the cylinder as does the toe a',.so that the eog'inecylinder may be lifted from .its base thereby.

llt-Will he olfnf'ious that the device 4may be disconnected troni the cylinder as readily as it wasl attached thereto. l
